- LINCOLN BLAKE, OF SAN FRANCISCO. CALIFORNIA, ASSIGNOR TO GEORGE PONAROUSE. OFSAN FRANOISGQ'OALIFORNIA' SAFETY COLLAR-BUTTON.

SPECIFICATION forming part of Letters Patent No. 768,167, dated August Application filed February 3, 1904. Serial No. 191,888. (No model.)

To all whom it may concern:

Be it known that I, LINCOLN'BLAKE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Safety Collar-Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates tocertain improvements in safety collar-buttons; and it has for its objects to produce a button of this character which will possess all the requisites of strength and durability and which will be especially simple in construction and efficient in operation.

In a large number of collar-buttons now in use in which the headis turned or otherwise manipulated to facilitate its ready insertion in the buttonhole springs or other delicately-pivoted parts are employedto hold the head in its several positions, thereby rendering the button incapable of withstanding severe and constant usage. In my button I have obviated the necessity of resorting to sucha delicate make-up and in addition have employed a construction which makes it possible to hold the head firmly in a set position as it is being inserted in the buttonhole, and thereby prevent the annoying and time-consuming buckling of the head, as is very apt to occur with the buttons now in general use.

Other objects and advantages of the invention will appear in the following specification, and the novel features thereof will be particularly set forth in the appended claim.

' I am, enabled to accomplish the above results by'the means illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the collarbutton, showing the head set ready for inser,

tioh in the buttonhole. Fig. 2 is a similar view showing the head in its normal position after it has been passed through the buttonhole. Fig. 3 is a side elevation of the button, the head being shown by means of dotted lines. Fig. 4: is-a transverse section taken in the direction of the line a: a; in Fig. 2. Fig.

5 is a central vertical section of the complete 4 hole after the button has been inserted. Fig.

7 represents'the next step in the operation of securing the button in place-z'. a, after the head has been drawn out from the stem. Fig. 8 represents the next stepi. 0.", after the head has been turned down at right angles to the stem. Fig. 9 represents the final'step a, after the head has been pushed along at right angles to the stem until it is equidistant on either side thereof.

Referringnow to the above views by letter, A represents the butt or base of the button, which is made inthe usual circular or disk form and is provided with the relatively rigid shank or stem B. This shank B is essentially U-shaped, with the opposite parallel legs a a and cross-bar b. Projecting inward from and integrally formed with the legs a and a are the lips c and 0, respectively, whichare slightly narrowed in thickness to form a T-shaped cross-section, as shown in Fig. i.

Encircling the cross-bar b and adapted to turn thereon is the head C. The butt 0? of this head C is contracted in width sufliciently to permit of its sliding between the inner .in the enlargedrview, Fig. 5.

' Now from the description so far gone into it will be readily seen that as the head C is placed in the relative position as shown in turning free of the collar oi garment until it assumes a position at right angles to the shank. The upper portion of the lips c and 0, directly beneath the cross-bar Z), I have cut away at f to permit the head being slid along at right angles to the shank until the central spread portion of the head reaches the cross-bar b, when the device is in its normal adjusted position.

From the above description it Will be readily seen that I have provided a very simple, durable, inexpensive, and compact collar-button capable of performing all the functions above set forth.

I am'aware that various changes in the form and proportion of parts of the several devices herein shoWn as an embodiment of my invention can be made Without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall Within the scope of my invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

A collar-button formed with a suitable base, a shank formed with opposite parallel legs and projecting from said base, a cross-bar connecting said legs, a head formed with an elongated slot and straddling said cross-bar, said head being arranged to slide through a cutaway portion in said legs and in a direction at right angles to said legs, said head being contracted in width suiiieiently to engage said legs and guide said head as it is slid in a direction perpendicular to said base and prevent said head from turning relative to said base, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

LINCOLN BLAKE.
